Description

The transmission rig of a kind of track type facility
Technical field
The present invention relates to a kind of transmission rig, particularly relate to the transmission rig of a kind of track type facility.
Background technology
Transmission mechanism is the middle device that the power of primover is passed to working mechanism. For track type facility, the power of primover transfers to crawler belt by transmission rig, thus realizes the driving of track type facility and turn to, and ensures the normal operation of track type facility. Turning to of track type facility can be divided into three kinds of modes, is respectively that trimming turns to, differential turns to and zero turn radius. Trimming turns to and is mainly used in turning between track type facility stop, and when facility need to turn between stopping, a crawler belt hangs low speed gear, and a crawler belt hangs neutral gear, does not have Power output owing to hanging the crawler belt of neutral, and facility then complete to turn to hang neutral gear crawler belt center as the center of circle. Differential turns to and is mainly used in turning between track type facility are advanced, two crawler belts of facility export different speed respectively, make a crawler belt of facility be in high gear, and a crawler belt is in low-grade location, the speed produced due to two crawler belts is different, and facility are then to low speed crawler belt directional steering. Zero turn radius be mainly used in track type facility stop between turning to, two crawler belts of facility export the speed of same transmitting ratio respectively, advance shelves, another reverse gear, and facility are then taking car body center as the center of circle, it is achieved pirouette to.
Usually, track type facility mainly adopt following three kinds of modes to realize transmission: 1, mechanical friction clutch realizes driving or turning in conjunction with multi-stage gear transmission; The trimming that this kind of transmission rig only can realize facility turns to, and the scope of application is little, and the performance requriements of clutch coupling is higher, has both required that clutch coupling can reliably transmit moment of torsion, in conjunction with after do not produce skidding, when requiring again clutch separation thoroughly, rapidly. Meanwhile, this kind of structure is not suitable for outside load and significantly changes or turn to and operate operation frequently. 2, multi-stage gear drive to differential mechanism again in conjunction with ended stop realize drive and turn to. This kind of transmission rig can make facility realize trimming to turn to and turn to differential, cannot realize zero turn radius; Which is higher to the performance requriements of ended stop, require that two side brakes export the proportional damping force of sizes and export enough braking moments and brake another side to realize differential and turn to or require two side brake sides and do not export damping force trimming turns to realize, making it export a certain proportion of damping force to need to adopt comparatively accurate electrical control system, cost is higher. 3, hydro-pump is exported to driving that two oil motors drive crawler belt to realize facility by independent hydraulically controlled controlling elements and is turned to; Hydraulic control component is generally servo-valve, and namely the two-way hydraulic oil pipe of hydro-pump connects two servo-valves respectively, and two servo-valves control two oil motors more respectively and carry out transmission. This mode can make up the defect of above-mentioned two kinds of modes, it is possible to realizes that trimming turns to, differential turns to and zero turn radius three kinds of steering modes, is the most common type of drive of current track type facility.
At present, although adopting the third mode can realize the driving of track type facility and trimming turns to, differential turns to and zero turn radius three kinds of steering modes, but, owing to transmission process needing adopt the servo valve control system of high precision strictly to control the motivating force of both sides oil motor, to ensure the traveling that track type facility are steady, safe, therefore, the manufacture of this kind of implementation, maintenance, use cost are all higher. Meanwhile, the transfer efficiency of hydraulic pressure, usually below 80%, causes the waste of energy, and therefore, the efficiency of hydraulic transmission mode is low, loss is big.

In the present embodiment, reversing system 8 is connected with the first sun gear 42 or the 2nd sun gear 52. Namely when reversing system 8 is connected with the first sun gear 42, first planet transmission rig 4 carries out the inverse composition of two power and retarded motion by reversing system 8, and the 2nd epicyclic transmission mechanism 5 then carries out the Synthesis in the same way of two power and accelerated motion; Namely when reversing system 8 is connected with the 2nd sun gear 52, the 2nd epicyclic transmission mechanism 5 carries out the inverse composition of two power and retarded motion by reversing system 8, and first planet transmission rig 4 then carries out the Synthesis in the same way of two power and accelerated motion.
